Comparison of Self-administered IPSS Sanitary Staff-supervised IPSS Medical History and Clinical Parameters


Brief description of study

Descriptive prospective study carried out to compare the results obtained by self-administered IPSS (International Prostate Symptom Score), Sanitary staff-supervised IPSS and directed medical interview and its correlation with clinical parameters in the assessment of lower urinary tract symptoms in males.

Detailed Study Description

The IPSS is a validated questionnaire (also in spanish language) widely used to evaluate lower urinary tract symptoms (LUTS) in males. It contains 7 multiple-choice questions related to urinary symptoms with a Likert response scale and 1 question assessing quality of life. This test has been approved for self-administration and its purpose is quantifying and monitoring symptoms severity.

The aim of this study is to compare the scores achieved in a self-administered IPSS questionnaire with those obtained when the questionnaire is answered with the help and supervision of a sanitary staff. These results will also be contrasted with the scores retrieved in a standard directed medical interview and correlated with objective functional parameters of lower urinary tract symptoms.

A descriptive prospective study will be carried out analysing lower urinary tract symptoms from patients over 50 years old.

All patients will be provided with a IPSS to be fulfilled at home and after a short period of time without any change in his LUTS treatment, the patient will repeat the questionnaire in the hospital under the supervision of a sanitary staff.

A standard structured medical interview focusing in LUTS will be performed to every patient. In order to compare the results achieved with both IPSS with those obtained during the interview a Likert score was assigned to each question.

At the same time, objective lower urinary tract symptoms data will be collected and compared to the results obtained previously with both the questionnaires and the medical interview. Uroflowmetry and post physiological void residual volume measurement with ultrasonography will be performed as evaluation of voiding symptoms. On the other hand, filling symptoms will be evaluated with a validated 3-day voiding diary to be accomplished previously to the medical visit.

Data to be collected includes Uroflowmetry parameters Qmax, Qm, curve shape type and time to Qmax, ultrasonographic PVR (post-void residual) measurement and daytime and nightime number of voids, medium volume of void, number of urgency and urge incontinence episodes and maximal vesical functional volume wich will be extracted from the 3-day voiding diary.

A statistical analysis will be performed to compare the scores obtained through the questionnaires and the medical interview and the correlation of each of them with the objective clinical parameters obtained.
